TUBULAR-BAR amen.

Application filed May 31,

' This invention relates to automobile bumpers and more particularly to a type of bumper using bars with curved tips thereon to form an impact section.

It is the principal object of this invention to provide a bumper using a plurality of interchangeable tubular bars as an impact section, said bars having their ends curved and being capable of being positioned in such a manner as to form a bumper with diverging or converging impact areas at its ends.

' Another object is to provide a clamping means for holding the tubular bars in vertical alignment.

A clear conception of the construction and further objects of the invention may be had from the following specification in conjunction with the accompanying drawings in which,

99 Fig. 1 discloses the preferred form of the invention in front elevation.

' Fig. 2 is a plan view of Fig. 1. FFig. 3 is a cross section through 3-3 of ig. 1. Y

Fig. 4 is a modified form of the invention in front elevation. v

- Fig. 5 is a plan view of Fig. 4.

Fig. 6 is a cross section through 6-6 of Fig. 4; and Fig. 7 discloses a further modified form in front elevation. I

The now preferred form of the inventlon as shown in Fig. 1 comprises three bars 1, 2, and 3 of tubular steel having their ends formed in a curved horn shape. These bars are all of the same length and have the same degree of curvature at their ends. The bars 1, 2, and 3 are held in vertical alignment and secured to a rear bar 5 by clamps 4 which are shown in cross section in Fig. 3.

The rear or attaching bar 5 has loop ends thereon and the center portion is brought forwardas shown, the loop ends and center portion being secured to the impact section by clamps such as 4. To simplify the descnption the clamp and front plate are designated by the same numeral. The clamp consists of a front plate 4 having a device or design on its face as shown, with holes for accommo- 5 dating bolts 6. The center portion 7 of the front plate is hollow with the edges of the plate formed with semi-circular recesses to accommodate the tubes 1, 2 and 3. The rear plate 8 is similar to plate 4 with the exception that it has a recess 9 formed in the center of 1927. Serial No. 185,158.

its rear face for accommodating the rear bar 5 as shown in Fig. 3. The plate 10 with holes therein for accommodating bolts 6is adapted to be positioned against the rear bar 5 when 1t is in the recess 9 and the whole clamp is secured about the bars by means of the bolts 6 and nuts 11. The bars 1 and 3 are positioned as shown with their ends turned to form a bumper with wide or divergent impact areas at its end. A modified orm of the invention as shown 1n Fig. 4 comprises an impact section of two tubular bars 12 and 14 to which the rear bar 15 is attached by clamps 16. The rear bar is similar to that described above with the exception that the loop ends are extended laterally to form a secondary impact portion positioned between the bars 12 and 14. The bar 15 is wider than the space between the bars 12 and 14. The clamp comprises a front plate 16 formed as shown with its center portion hollowed out as described above and the edges of the plate adapted to grip the bars 12 and 14. The front plate is provided with a hole for accommodating a bolt 17 The rear plate 18 is formed similar to that described above for clamp 4having a recess 19 therein for accommodating the rear bar 15. The rear plate 18 and the bar 15 are provided with holes for accommodating the bolt 17 and the whole clamp is secured about the bars 12, 14, and 15 by means of the bolt 17 and nut 20.

This type of bumper has its bars 12 and 14 positioned as shown to form a wide impact area at its ends with a rear bar 15' interposed to form a secondary impact section at the ends of the bumper.

A further modification of the invention is shown in Fig. 7 in which a rear bar 5 is combined with a pair of tubular bars 22 and 23 which are secured invertical alignment by a clamp 16. As is seen from the drawings the bars 22 and 23 are positioned with their tips turned toward each other thereby formng a multi-bar bumper with a curved and we tapered end, thereby giving a converging or narrowed impact area at its ends.

The above types of bumpers are assembled loosely in their respective clamps, and as the bars are all of the same length and their nos tips of the same degree of curvature they are interchangeable. The bars are adapted to be turned until any of the desired forms of end sections as shown in Figs. 1, 4, and are attained. The clamps are then tightened to no hold the bars securely in place and the bumper is read for mstallationon a vehicle. Due to e fact that the bars are all of the same length and their ti s are of the I same curvature the bars are easi y nested for shipment. r c

It is-apparent that the bars of this type of bumper may be axembled with their tip ends parallel without departing from the scope of this invention. .v

' I claim:
